Description

Technical Field

[0001] This utility model relates to the technical field of automated thermal processing, and in particular to a feeding device for a heating electric furnace. Background Technology

[0002] This invention relates to the field of automated thermal processing technology, and in particular to a feeding device for a heating electric furnace, used to transport and position high-temperature cylindrical blanks that have been heated and exited the furnace, so as to facilitate subsequent die casting or cutting of flanges.

[0003] In forging production lines for ring-shaped components such as flanges, cylindrical metal billets must first be heated to extremely high forging temperatures in a heating furnace. Then, a discharge mechanism pushes them onto a conveyor, such as a roller conveyor, for rapid transport to the next station. There, a pick-up device, such as a robotic arm or specialized clamps, grasps the billet and places it into a die-casting mold or cutting equipment. The continuity and precision of this process directly determine the production cycle time and the quality of the final product.

[0004] Because the cylindrical billets just output from the heating furnace are at extremely high temperatures, their surface oxide scale has peeled off, their physical state is unique, and they carry a large amount of heat energy. When running on the conveyor, due to inertia and conveyor vibration, the billets are prone to rolling, deviating, or stopping, resulting in a lack of uniform stopping posture in both the axial and circumferential directions when they reach the predetermined picking position.

[0005] Currently, a Chinese utility model patent with publication number CN221621588U and publication date of August 30, 2024, proposes a feeding structure for continuous processing of flanges, including: a conveyor belt, a servo motor, a rotating shaft, multiple rotating rods, and a clamping assembly. The servo motor drives the rotating shaft and rotating rods to drive the clamping assembly to rotate along the rotating shaft, thereby realizing continuous clamping of flanges. The flanges on the production line or conveyor are clamped by the cooperation of a cylinder and an arc-shaped rubber pad.

[0006] Regarding the aforementioned technologies, the easy displacement of the billet position and the high temperature and heat radiation of the billet limit the reliable use of ordinary sensors, making it difficult for the feeder to perform real-time and accurate visual positioning or detection of the billet, and unable to provide accurate correction signals for the feeder, which seriously affects the normal gripping of the billet by the feeder. Utility Model Content

[0007] In order to solve the problem of inaccurate positioning of billets on the conveyor and enable the feeder to accurately pick up the billets, this utility model provides a feeding device for a heating electric furnace.

[0008] This utility model provides a feeding device for a heating electric furnace, which adopts the following technical solution: A feeding device for a heating electric furnace includes a frame and a conveyor, the conveyor being mounted on the frame; it also includes a support frame, a support plate and a positioning mechanism, the bottom end of the support frame being fixedly connected to a preset position, the top end of the support frame being inserted between the conveyor rollers on the conveyor, and the support plate being fixedly mounted on the top end of the support frame; The positioning mechanism includes a mounting plate and an adjusting plate. The two mounting plates are mounted opposite each other on the upper end of the support plate. The adjusting plate is fixedly mounted on the mounting plate, and a positioning plate is fixedly mounted on one end of the adjusting plate.

[0009] Preferably, one end of the positioning plate extends into an arc-shaped segment.

[0010] Preferably, a plurality of heat insulation strips are fixedly installed on the positioning plate, and one side of the heat insulation strips is arc-shaped.

[0011] Preferably, the positioning plate and the adjusting plate are fixedly connected by bolts.

[0012] Preferably, the positioning mechanism further includes a fixed seat, an adjusting rod, and an adjusting sleeve. One end of the fixed seat is rotatably connected to the adjusting plate, and the other end of the fixed seat is rotatably connected to the adjusting sleeve. One end of the adjusting rod is threaded into the adjusting sleeve, and the other end of the adjusting rod is rotatably connected to the positioning plate.

[0013] Preferably, the adjusting plate has multiple adjusting holes, one end of the adjusting plate slides through the mounting plate, the mounting plate has an adjusting shaft passing through it, the adjusting shaft passes through the adjusting holes, and the adjusting plate is fixedly mounted on the mounting plate via the adjusting shaft.

[0014] Preferably, the bottom end of the mounting plate is rotatably connected to the support plate, one end of the mounting plate is provided with an adjustment slot, a sliding plate is slidably mounted on the support plate, a sliding rod is mounted on the sliding plate, the sliding rod slides in the adjustment slot, a first mounting seat is fixedly mounted on the support plate, a second mounting seat is fixedly mounted on the upper end of the sliding plate, an adjustment screw is rotatably mounted on the first mounting seat, and the adjustment screw is threadedly connected to the second mounting seat.

[0015] In summary, this utility model has at least one of the following beneficial technical effects: 1. The positioning mechanism, interspersed between the conveying rollers, can actively intervene in the high-temperature billet during conveying. Two opposing positioning plates form a gradually concave guide channel, effectively correcting the rolling and deviation of the billet, and accurately stopping it at the predetermined picking position, thus solving the problem of the picker failing to hold the billet due to uncertain position.

[0016] 2. The heat insulation strip prevents the metal positioning plate from directly contacting the surface of the high-temperature blank, thus preventing scratches on the oxide scale on the blank surface or causing micro-cracks due to "rapid cooling" of the blank, ensuring the quality of products processed subsequently.

[0017] 3. By rotating the adjusting sleeve with a tool, the extension and retraction of the adjusting rod within the adjusting sleeve can be precisely controlled, thereby causing the positioning plate to rotate and adjust around the bolt, thus adjusting the angle of the positioning plate. During equipment operation, the operator performs fine calibration of the positioning point to compensate for thermal deformation of the equipment or to adapt to the precise requirements of different specifications of blanks, ensuring the absolute accuracy of the feeder's clamping position.

[0018] 4. Angle adjustment is achieved by adjusting the through groove, sliding plate, and sliding rod, allowing for precise setting of the included angle and centerline of the guide channel formed by the two positioning plates based on the material's conveying trajectory and final stopping position. This better adapts to different conveying speeds and friction coefficients, ensuring the material is precisely guided to the unique and correct pick-up point, achieving optimal positioning results.

[0025] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0026] This utility model discloses a feeding device for a heating electric furnace. (Refer to...) Figures 1 to 5A feeding device for a heating electric furnace mainly includes a frame 1 and a conveyor 2, with the conveyor 2 mounted on the frame 1; it also includes a support frame 3, a support plate 4, and a positioning mechanism 5. The bottom end of the support frame 3 is fixedly connected to a preset position, and the top end of the support frame 3 is inserted between the conveyor rollers on the conveyor 2. The support plate 4 is fixedly installed on the top end of the support frame 3. The positioning mechanism 5 includes a mounting plate 6 and an adjusting plate 7. The two mounting plates 6 are mounted opposite each other on the upper end of the support plate 4, and the adjusting plate 7 is fixedly installed on the mounting plate 6. A positioning plate 20 is fixedly installed on one end of the adjusting plate 7.

[0027] The rigid frame formed by the support frame 3 and the support plate 4 allows it to withstand the heat radiation and potential deformation of the high-temperature environment, providing a stable foundation for precise positioning. The positioning mechanism 5, interlaced between the conveyor rollers, actively intervenes in the high-temperature billet during conveying. Two opposing positioning plates 20 form a gradually concave guide channel, effectively correcting the rolling and offset of the billet, ensuring it stops accurately at the predetermined picking position, thus solving the problem of the picker failing to grip the billet due to uncertain position. This solves the problem of inaccurate positioning of the billet on the conveyor 2, enabling the picker to accurately grip the billet.

[0028] Reference Figure 2 In some embodiments, one end of the positioning plate 20 extends into an arc-shaped segment. The arc-shaped segment forms a funnel-shaped inlet. When a misaligned high-temperature blank comes into contact with the plate, it can be smoothly "captured" and guided into the positioning channel, greatly reducing jamming or rebound caused by rigid collisions.

[0029] Reference Figure 3 In some embodiments, multiple heat-insulating strips 8 are fixedly installed on the positioning plate 20, with one side of each heat-insulating strip 8 being arc-shaped. The heat-insulating strips 8 can be made of high-temperature resistant ceramics, asbestos, or other materials, effectively blocking direct heat transfer from the high-temperature blank to the positioning plate 20 body, preventing the positioning plate 20 from deforming, degrading, or being damaged due to overheating, and extending its service life. Direct contact between the metal positioning plate 20 and the surface of the high-temperature blank is avoided, preventing scratches on the oxide scale of the blank surface or causing micro-cracks due to "rapid cooling," thus ensuring the quality of products processed subsequently.

[0030] Reference Figure 3 In some embodiments, the positioning plate 20 and the adjusting plate 7 are fixedly connected by bolts. This connection method allows the positioning plate 20 to be disassembled and replaced individually and quickly, which greatly simplifies maintenance and reduces downtime, especially under harsh working conditions of high temperature and high wear. At the same time, the positioning plate 20 can be rotated by loosening the bolts, and then tightened to fix it to the positioning plate 20 after reaching a specified angle, thus enabling angle adjustment.

[0031] Reference Figure 3 and Figure 4 In some embodiments, the positioning mechanism 5 further includes a fixed seat 9, an adjusting rod 10, and an adjusting sleeve 11. One end of the fixed seat 9 is rotatably connected to the adjusting plate 7, and the other end of the fixed seat 9 is rotatably connected to the adjusting sleeve 11. One end of the adjusting rod 10 is threaded into the adjusting sleeve 11, and the other end of the adjusting rod 10 is rotatably connected to the positioning plate 20. By rotating the adjusting sleeve 11 with a tool, the extension and retraction of the adjusting rod 10 within the adjusting sleeve 11 can be precisely controlled, thereby driving the positioning plate 20 to rotate and adjust around the bolt, thus adjusting the angle of the positioning plate 20. During equipment operation, the operator performs fine calibration of the positioning point to compensate for equipment thermal deformation or adapt to the precise requirements of different specifications of blanks, ensuring the absolute accuracy of the gripper's clamping position.

[0032] Reference Figure 3 In some embodiments, the adjusting plate 7 has multiple adjusting holes 12. One end of the adjusting plate 7 slides through the mounting plate 6, and an adjusting shaft 13 passes through the mounting plate 6. The adjusting shaft 13 passes through the adjusting holes 12, and the adjusting plate 7 is fixedly mounted on the mounting plate 6 via the adjusting shaft 13. The multiple adjusting holes 12 provide several discrete, quickly selectable positioning positions. By changing the extension length of the adjusting plate 7, the distance between the two positioning plates 20 can be significantly adjusted, thereby enabling the device to adapt to cylindrical blanks of different lengths and significantly improving the flexibility of the production line.

[0033] Reference Figure 4 and Figure 5 In some embodiments, the bottom end of the mounting plate 6 is rotatably connected to the support plate 4. One end of the mounting plate 6 has an adjustment groove 14. A sliding plate 15 is slidably mounted on the support plate 4, and a sliding rod 16 is mounted on the sliding plate 15. The sliding rod 16 slides within the adjustment groove 14. A first mounting seat 17 is fixedly mounted on the support plate 4, and a second mounting seat 18 is fixedly mounted on the upper end of the sliding plate 15. An adjustment screw 19 is rotatably mounted on the first mounting seat 17, and the adjustment screw 19 is threadedly connected to the second mounting seat 18. By rotating the adjustment screw 19, the sliding plate 15 can be driven to move, and then, through the cooperation of the sliding rod 16 and the adjustment groove 14, the mounting plate 6 can rotate around its hinge point. This allows for angle adjustment, enabling the user to precisely set the included angle and centerline of the guide channel formed by the two positioning plates 20 according to the material's conveying trajectory and final stopping position. This better adapts to different conveying speeds and friction coefficients, ensuring that the material is precisely guided to the unique and correct pick-up point, achieving optimal positioning results.

[0034] The implementation principle of the feeding device for a heating electric furnace according to this utility model embodiment is as follows: The positioning mechanism 5, consisting of two relatively positioned plates 20 forming a gradually concave guide channel, can actively correct the rolling and deviation of the high-temperature billet during conveying, ensuring that it stops precisely at the predetermined picking position, thus solving the problem of clamping failure caused by uncertain position. The heat insulation strip 8 installed on the positioning plate 20 effectively avoids direct contact between the metal parts and the high-temperature billet, preventing scratches on the oxide scale on the billet surface and eliminating micro-cracks caused by rapid cooling, thus ensuring the processing quality of subsequent products. The angle of the positioning plate 20 can be precisely controlled by rotating the adjusting sleeve 11, ensuring the accuracy of the clamping position of the picker.

[0035] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
